connect to database from widget class

Question

in widget Receiver class that extend AppWidgetProvider when i want to connect to database helper class for fetching some data by this statement i get some error:

public class wigetactivity extends AppWidgetProvider {

@Override
public void onUpdate(Context context, AppWidgetManager appWidgetManager,int[] appWidgetIds) {

    final DataBaseHelper myDbHelper = new DataBaseHelper(this);
         .
         .
         .
        }

i get this error: The constructor DataBaseHelper(wigetactivity) is undefined

my database helper class and constructor definition is:

public class DataBaseHelper extends SQLiteOpenHelper {
            public DataBaseHelper(Context context) {
    super(context, DB_NAME, null, 1);
    this.myContext = context;
}

 }

in a regular class that extends Activity i connect successfully to database, How i can fix that?

please post the whole stack trace and the code context when you create your helper, so we can see what this refers to — Raffaele

Instead of using this (which is not a Context in this case), use the provided context:

  final DataBaseHelper myDbHelper = new DataBaseHelper(context);
